I know this isn't a popular opinion, but I learned a lot when I started the Google Glass project. A key insight was how important human eye contact is.
Removing the ability to see someone's eyes when talking with them negatively changed the entire dynamic.
So, while I am impressed with Meta's new glasses, they continue the huge error (imho) of blocking eye-to-eye contact.
I don't think any glasses that are dark / block you from seeing another person's eyes will have mainstream, broadly appealing success.
